Well, since you're already an Android user, if you kept your business contacts on your Droid X using Google Contacts, then those contacts will also be on your Xoom. That's if you're using the same Google account on the Droid X and the Xoom. Yes, you can use the same Google account on multiple devices. I use the same Google Account on my HTC EVO and my Xoom. What this also means is, if you already purchased apps for your Droid, you will not have to purchase them again to use on the Zoom, since the purchase history is stored on your Google Account, not by device.
Basically, as long as you're using Google's cloud technology (Google Calendar, Google Contacts, Gmail), you should have no worries syncing between both devices.
